Studies in Waxes. XIX. The Stem Wax of the Grass Leptochlona digitata

Abstract

The stem wax of the grass Leptochloa digitata (R.Br.) Domin. has been examined mainly by gas chromatographic methods. The wax after hydrolysis has been shown to consist largely of straight-chain acids (54%) and n-paraffin hydrocarbons (21%). Straight-chain alcohols and ketones are also present, along with other alcohols and ketones which were not examined. A feature of the wax is the presence of small amounts of hydrocarbons with very long chains (2.5%) from which n-dohexacontane (C₆₂H₁₂₆) has been isolated and identified by its X-ray long spacing and melting point.
